Preference for double-patch technique in adult patients with partial anomalous pulmonary venous return.

INTRODUCTION

Partial anomalous pulmonary venous return (PAPVR) can be treated with either the single- or double-patch technique. In this study, we evaluated the results of both techniques in adult patients with PAPVR.

METHODS

We reviewed the records of 29 patients treated for PAPVR in two groups, according to which surgical technique was used.

RESULTS

Double- and single-patch repair techniques were performed in 12 (group 1) and 17 patients (group 2),respectively. In group 2, three patients with a distance of more than 10 mm between the ostium of the anomalous pulmonary vein and the cava-atrial junction needed surgical re-intervention because of superior vena cava stenosis. There was no sinus node dysfunction and no mortality in either group.

CONCLUSION

In adult patients with PAPVR, the double-patch repair technique revealed better results than the single-patch technique, especially in patients with the ostium of the distal anomalous pulmonary vein more than 10 mm from the cava-atrial junction.
